Figure 7.11 – Platform
To inspect the guardrail system:
1. Visually inspect all components of the guardrail
system. Make sure the rails and toeboards are all
in place and free of any damage or deformation.
2. Visually check the rail and toeboard welds for
cracks.
3. Visually check all bolts and nuts fastening the plat-
form and guardrails in place. They must be present
and not show any signs of looseness.
4. Inspect the entry gate to see that it swings freely
and is not deformed in any way. Make sure the door
is secure when it is closed.

Platform Extension

Latch handles on each side of the extension deck
secures the extension deck to the main platform deck.
Caution
The extension deck is free to move when the exten-
sion handle locks are disengaged. Personal injury
may result from accidentally extending or retracting
the deck. Make certain both extension handle locks
are fully engaged when the deck is extended in the
working position and when it is stowed. Do not at-
tempt to extend or retract the platform unless the
aerial platform is on a level surface.
To inspect the platform extension:
1. Inspect the extension handles and locks (refer to
Figure 7.12) on each side of the platform to ensure
they release to extend the platform.

2. While facing the front of the platform, grasp the
platform extension handles, raise them and push
the extension deck forward to extend the deck.
Fully lower the handles at the mid or front position
and ensure they are locked in their lowered position
(refer to Figure 7.12).
3. Inspect the rollers on the platform extension. They
must be in place, in good condition, and free to
move without obstruction.
4. Inspect the weldments for deformation and damage.
Try to move the rails back and forth to make sure
the platform extension deck fully locks in position.
5. Visually check the platform welds for cracks.
6. While facing the front of the platform, grasp the
platform extension handles, raise them and pull the
extension deck backward to retract the deck. Fully
lower the handles at the stowed position and ensure
they are locked in the lowered position (refer to Figure
7.12).
7. Make sure the platform extension deck is locked in
position.

Operating Controls

Warning
The potential for an accident increases from improp-
erly driving or steering the aerial platform. Death
or serious injury could result from such accidents.
Make sure the upper control panel is securely fas-
tened inside the platform and facing the front of
the machine.
Avoid driving the platform with the upper controls fac-
ing the rear or side of the machine. In this position the
machine is diffi cult to control because the drive and
steer control movements and their resulting machine
movements will not correspond.
Only operate the upper controls when the upper control
panel is securely fastened inside the platform and facing
the front of the machine.
Use the following procedure to operate and test the
machine from the upper controls:
